Abstract (en)
[origin: US2002176497A1] Provided are a quantizing unit setting apparatus that enable suppressing the deterioration in the quality of image after coding in a distribution origin to thereby suppress the deterioration in the quality of image after decoding in a distribution destination. In the quantizing unit setting apparatus, there is equipped a quantizing step setting part in which there is predicted an empty memory space in memory device for temporarily storing the produced coded moving picture, and the empty memory space, if there are coded the original static picture images, there is set the quantizing unit according to the predicted empty memory space so as to prevent the memory device from overflowing.
